PEEFACE. 


THIS  little  book  contains  brief  descriptions  of  over  five  hundred 
species  of  plants  known  to  grow  in  the  region  bounded  on  the  west 
by  the  coast  line  from  Monterey  Bay  to  Mendocino  County,  and  on  the 
east  by  the  foothills  of  the  Sierra  Nevada.  Only  polypetalous  and 
gamopetalous  exogens  are  described,  and  of  these  the  orders  Umbelliferse 
and  Composite,  with  a  few  inconspicuous  plants  of  other  orders,  are 
omitted,  being  considered  too  difficult  for  beginners. 

The  descriptions  are  mainly  abridged  from  the  large  work  on  Cali- 
fornia Botany  published  in  uniformity  with  the  Geological  Survey  Reports. 
The  Analytical  Key  is  essentially  the  one  prepared  for  that  work  by  Dr. 
Asa  Gray.  Several  names  are  changed  and  a  few  descriptions  modified 
in  accordance  with  "Gray's  Synoptical  Flora  of  North  America/' 

Usually  only  contrasting  characteristics  of  species  are  retained,  since 
anything  more  is  confusing  rather  than  helpful  to  the  beginner.  The 
habitat  of  plants  is  given  only  when  it  would  be  of  assistance  in  deter- 
mining species. 

All  established  common  names  are  given.  Fortunately  our  most 
beautiful  plants  are  well  known  by  their  proper  generic  names. 

A  Second  Part  devoted  to  the  Apetalse  and.  Edogenous  plants,  with  an 
Introduction  to  Systematic  Botany  will  probably  be  issued  within  a  year. 

Correspondents  will  confer  a  favor  by  pointing  out  errors  and  omis- 
sions. V.  E. 

SAN  FRANCISCO,  February,  1879. 


DIRECTIONS   FOR    THE    LEARNER. 


AT  first  study  only  those  plants  which  have  large  flowers.  Do  not 
attempt  to  determine  the  name  of  a  plant  unless  you  have  specimens 
which  show  not  only  the  flowers,  but  the  buds,  the  fruit  (at  least,  partly 
grown),  the  leaves  from  all  parts  of  the  stem,  and  the  roots.  If  you  can- 
not readily  distinguish  the  parts  of  the  flower  and  their  relations  to  each 
other,  lay  it  aside  until  the  study  of  easier  plants  has  given  you  more 
skill. 

If  the  small  veins  of  the  leaves  do  not  form  a  network,  and  the 
organs  of  the  flower  are  all  in  threes,  the  plant  is  probably  an  endogen 
and,  therefore,  not  described  in  this  book.  If  the  calyx  and  corolla  are 
not  both  present  the  flower  is  said  to  be  apetalous.  A  few  such  flowers 
are  described,  and  the  orders  are  to  be  sought  under  the  last  division  of 
the  Analytical  Key.  Clematis,  Allolropa  and  Glaux  are  apetalous  genera 
having  the  calyx  corolla-like. 

It  will  be  best  to  write  out  a  description  of  the  plant  before  attempt- 
ing to  analyze  it.  Some  good  text-book,  such  as  Gray's  "  How  Plants 
Grow,"  should  be  constantly  referred  to  in  search  of  the  proper  descrip- 
tive terms.  Suppose  the  following  to  be  a  description  of  the  plant  in 
hand,  the  words  in  parentheses  indicating  a  more  concise  way  of  telling 
the  same  thing:  A  hairy  plant  one  or  two  feet  high,  with  opposite  leaves 
and  no  stipules  (exstipulate);  the  leaves  narrow  and  blunt,  broader  near 
the  upper  end  (spatulate);  the  small  pinkish  flowers  growing  on  short 
stems  (pedicels)  close  together  along  one  side  of  the  main  stem  for  sev- 
eral inches  to  the  end  (in  a  close  raceme);  the  calyx  of  5  sepals  united  to 
form  a  narrow  tube  (tubular,  5-lobed)  nearly  half  an  inch  long,  marked 
by  10  ridges  (nerves);  the  5  petals  distinct  from  each  other  and  very  nar- 


6  BISECTIONS   FOR   THE   LEARNER. 

row  inside  the  calyx  (clawed),  the  part  outside  (blade)  short  and  rounded, 
broadest  near  the  end  (obovate);  two  little  teeth  standing  up  on  each 
petal  just  where  it  bends  outward  from  the  calyx  (blade  2-appendaged 
at  the  base);  the  petals  twisted  so  as  to  make  one  edge  higher  than  the 
other;  stamens  10;  pistil  one,  with  three  short  straight  styles  and  a  short 
stem  below  the  ovary  (stipe)  on  which  the  petals  and  stamens  grow;  the 
seed  pod  (capsule)  ovoid  and  rough,  containing  seeds  which  grow  fast  to 
a  central  part  (placenta). 

Turning  to  the  Analytical  Key,  we  determine  that  it  belongs  under 
Division  1,  because  the  petals  are  separate.  Since  our  plant  cannot  be- 
long under  A,  the  stamens  being  only  10,  we  turn  to  "  B.  Stamens  10  or 
less/'  etc. ;  under  this  head  we  read:  "  1.  Ovary  or  ovaries  superior,"  etc. , 
which  is  the  case  with  our  plant;  then  follows:  "*  Pistils  more  than  one 
and  distinct;"  but  there, is  only  one  pistil  in  our  flower,  so  we  pass  on  to 
c<  *  *  Pistil  only  onet"  below  which  is  "  4—  Simple,  i.  e.,  of  one  carpel,  as 
shown  by  single  style,"  etc.,  but  there  are  three  styles  in  the  pistil  of  our 
flower,  so  we  try  "  -\ — h-  Pistil  compound,"  etc.,  which  suits  our  case;  then 
we  read  the  next  line,  but  upon  looking  up  the  word  "placenta,"  con- 
clude that  our  plant  cannot  be  found  under  that  head;  the  next  line  of 
the  same  length  does  not  suit  because  our  pod  is  not  "  2-celled;"  but  the 
third  reads:  "Ovary  and  capsule  1-celled,  seeds  on  a  central  placenta/' 
which  applies  to  our  seed  pod;  in  the  next  line  "  Sepals  2;  fleshy  herbs  " 
is  wrong,  so  we  try  "  Sepals  5  or  4;  leaves  opposite,"  etc.,  which  leads 
us  to  ORDER  CARYOPHYLLACE.E,  p.  27.  The  description  of  the  order  is 
satisfactory.  Evidently  our  plant  belongs  to  the  first  genus  named  in 
the  Synopsis  of  Genera,  viz. :  Silene;  and  the  first  species  under  that 
genus  is  our  plant,  the  proper  name  of  which  is  Silene  Galica.  We  find, 
too,  as  we  always  shall,  that  some  things  were  omitted  in  our  description; 
also,  that  all  the  characteristics  of  the  plant  are  not  given  in  this  book. 
Having  determined  the  name,  you  should  next  write  out  a  description,  as 
nearly  complete  as  possible,  and  make  drawings  showing  the  outlines  of 
the  leaves  and  the  separate  parts  of  the  flower.

large,  the  separate  flowers,  with  but  few  exceptions,  are  too  small  to  be  examined  with-
